could you please help!
There was an issue on Flutter repository as mentioned by #amer rawashdeh.
iOS 13.4 is now available, please update your iOS device and Xcode to v11.4 to keep your project newly working.
If you are on Flutter stable channel you need also to apply this guide to keep you project working with v11.4 Xcode
It seems the problem with ISO version 13.3.1 only

My flutter app is crashing when I connect it to firebase and try to use it. It is only happening for this app(other apps are connecting fine). I am not sure why? Any suggestions would be greatly appreciated.I followed several tutorials and all of them did the same.
I have registered the app :
Provided bundle identifier
Attached the info-plist file
Flutter doctor :

Install Android Studio from: https://developer.android.com/studio/index.html
On first launch it will assist you in installing the Android SDK components.
(or visit https://flutter.dev/docs/get-started/install/macos#android-setup for detailed
instructions).
If the Android SDK has been installed to a custom location, please use
flutter config --android-sdk to update to that location.

I am trying to test my flutter application on my iPad, and iPhone, and I have tried everything that I've read from forums.
It will run on an emulator, but not a physical device.
I have tried:
Cleaning and rebuilding.
Restarting my computer.
Updating all of the software on both my computer and the devices.
Creating a unique bundle id.
Choosing different teams for signing.
Changing iOS development target.
Changing the bundle id to my email.
I'm just not sure what to fix at this point.
this is the output of flutter doctor:

There is something up with Xcode and my computer, because I downgraded to Xcode 11.3 and it worked.
For some reason, iOS Simulator stopped working. I can open iOS Simulator, but Android Studio not recognizes it. I've already tried to run via terminal, but it says not supported devices connected.
When I run flutter doctor it returns:

Since I'm on a Macbook 2011, I won't be able to upgrade Xcode. Is it possible to downgrade Flutter and Xcode to an older stable version? Would this solve the problem?
Thanks
If Android Studio does not recognize ios simulator even though you can separately open simulator on your Mac, you have to add command line tool on Xcode.
open Xcode then go to Xcode > preferences > select Locations tab. Then select Xcode version from the drop-down menu.
Open ios simulator again. Then Android Studio will recognize your device.
I have a mobile app in Flutter, it works fine on Android and iOS simulators as well as real devices (except only real iPads with iOS 12.0 and above)
The problem is with running the app in iPad - after the launch I see a white screen for 5 seconds, than a black screen for 3 seconds and that's the finish. The app is not running further.
It even does not show a launching screen.
I am testing in Firebase Test Lab and I have done flutter upgrade before every build of product.
And this is my flutter doctor:

Do you have any ideas what could it be?
Currently, there is an open bug about crashes that occurs on iPhones with the memory of 1GB or lower on most iOS 12. I suggest to upgrade your Flutter version to the latest. As of this writing, the latest version is 2.10.3 in stable channel.
I'm trying to build an archive by doing flutter build ios but I encounter a problem on Starting Xcode build
$ flutter build ios

I already build an archive one (last week) and it was working. Maybe this is due to flutter upgrade ?
$ flutter doctor

That's an issue that was fixed very recently and the fix should already be available in the master channel.
flutter channel master
flutter doctor
You can also try dev channel, but I'm not sure if it landed there already.
The fix will of course be included in the next beta channel, but a beta release just came out last week, so it will probably take a while to the next.
